Dual-mode fluorescence and colorimetric bimodal sensing of Baijiu based on the peroxidase activity of CDs@MOF

. The reducing substance effectively inhibited the formation of the oxidation substrate, resulting in alterations in fluorescence and UV intensities. The dual-mode sensor array was found to be effective in detecting 15 different types of reducing chemicals. Furthermore, the colorimetric and fluorescence sensor array demonstrated exceptional capability in detecting 19 different types of Luzhou-flavor liquor samples, obtaining flawless recognition results. This study will provide an accurate and rapid method for differentiating different types of Baijiu.
